Interesting climb to the crater, which you can walk around on a 7km long circular path on the crater rim. You will always get interesting views of the crater. In places you can also see fumaroles on the walls. The path should not be underestimated, as it is partly very washed out and difficult to walk, especially as you are mostly walking in the blazing sun. Added to this are the usually high temperatures in the area. Therefore, a good supply of water and provisions is very important.
